To all whom it may concern/.-

uBe it known that I, HUGO TUTEIN NOL- ferent points of attachment for the music paper.

' v IIHENIUS, asubject of the Queen of the Neth- I The roll a, that contains the music-paper U I-vented merits in Apparatus erlands, residing at Delft. Haagweg the Kingdomof the Netherlands, have inccrtain new for TIEIIISPOSIDQ- the ,Key-Note in the Performances of the Piantransposi'ng ola, of which the following is a specification.

This invention relates to an apparatus for or changing the kc '-note in i which a piece of music is performed bythe mechanical p1 anoforte-playerknown as the ,with the pianola. the subject of the 2b Other instruments of this kind arealready provided with means for transposmg the music or'changing the key-note;

notbeen the case The apparatus forming present invention there fore fills a felt want! The apparatus comprises a set of filling-up but heretofore this has pieces adapted to be placed between one end of the roll that contains the music-paper and s y one of the centers between which this roll ,inuslcpaper laterally in regard to the instrumerit.

turns in order to alter the position of the As is well known, the keys of the pianoforte that the pianolo actuates are roptogether in a tracker arranged parallel to the roll that contains the musicresented' by small suction-holes bored close between and paper and the roll on which the music-paper musical composition, and so are sounded on the pianofortc.

is wound up during the pcrformaneo'j 'lhe .niusic-paper, along fillet of paper perforated systematically, is tightly drawn over said tracker, closing all the suction holes except the notes of the these notes only X ow as the pitch of the suction-holes is uniform and corresponds to a semitone it is quite clear that tlio'se" which correspond to the moving of the paper laterally a distance (equal to that between two :nljaccnt holes has the ell'ect-ol' lowering or raising the key note of the mus cal composition a scnntonc and that moving the paper twice this distance has a double effect, and so on.

The pin cacts as a clutch-coupling in such away that the roll a, if necessary, can be turned round together with the axis It.

The pin (1 is slidable in, the well-known manner. it may be pressed back againstthe pressure of the spring and is guided by the support 71..

The n1usic-paper b on its way to the takeup roll '5 passes the trackerf I t is provided with an eye g, by means of which it is attached. to a hook /L on the roll 2'.

As Fig. 3 shows in the example here chosen,

, six hooks it are arranged in a helix on the, roll i, the distance between adjacent hooks measured laterally being. the same as that be tween adjacent holes in the tracker f; As the hooks k may not project beyond the surface of the roll i, a suitable recess is provided for them, Fig. 3.

Two of the filling-up pieces are illustrated in Fig. 2. They constitute V lengtheningpieces to the axis 1c and are shaped as clutchcouplings. The shortest piece (illustrated in the middle of the figure) is somewhat different in sha e from the other.

The ta .'-up roll '5 is rovided with two sliding bushings Z, furnis red with flanges or collars m, that arcintended to guide the pa per 1;. The parts of the framing of the instrument that support tl'ie'elcments here described are indicated by r. g is the toothgear by which the rolli is turned during the playing.

Thc fillingup pieces are used as follows: Let us suppose the V is wanted to be transposed into a key-note that differs from the original by two semitones or one whole notcj We choose the corresponding filling-up piece 7', that has a length equal to twice the distance between adjacent suction-holes o, and putting the roll 6 into the instrument we bring this piece 7' bctwgen the roll a and the pin 0, Fig. l, at the some time pushing back the spring-supported pin (land compressing the spring 4; as much as necessary. The paper is then attached to the take-up roll i by putt ing the eye 9 on the hook ii that corresponds to the center line of the musicpa )or, and the sliding bushings Z are moved til the employed hook it is in the middle beaccompaniincnt to a song-- fering by two half-notes from t The l note of the musical compo ion is altered as required. The perl'orrni ice ished, it is necessary to bring the music-pepe" from the roll 2' back on the roll. c. This i executed in the usual manner by disconn ing the gear (1 and turning the axis is back- Ward. The piece that is snaped to connect the axis it to the roll (a perm ts this motion. A set of live fillingnp pieces 9' will do very Well for general "use, this being transpose from tenor to boss.

The apparatus forming the su present invention may be appl en pisnola Without alterations or col mentioning. A pin d of sutticient necessary a recess p in the side permit the full movement oi the roll the removing from the lett-hand side of the IOllt of a collar that would not permit su'r'li' cient movement of the left sliding bush Z are the only points in which the instrmnent as previously made rosy require to be altered.
